Hingedly' mounted means of hinges 21a f 'the carrying reels 23. A The filmitself isl designated by the lettera. The `base 1 carries' a swinging plate 24 atI-each end, each said gaginga stud 25 on eachlleaf 3 tohold said leaves in extended position. When not in use these plates 24 may be swung into open position thereby allowing the leaves 3 to be folded into upright position, each leaf having a deback in open position the ilm 0, is drawn over the channel plate 8, over the drum ll and over the channel plate 9. The pads coveringthe channel plates 8 and le are saturated with the Y desired quantity o'l" a cleaning fluid Which is applicable to both sides of the lilm. rEhe channel plates i4- and l5 are then swung down upon the channel plates 8 and 9 respectively, the drum 1'? pressing down upon the film a. The clamping members 22 are then sprung into place and the heating member 20 is adjusted so that its rays play directly on the film. rlhe rewinder is then turned to draw the film through the clamps formed by the channel plates. Then passing through theclamp formed by the channel plates S and 14C the film is cleansed oi all grease spots` and receives a coating` of cleaning` iiuid. The excess liuid on the upper side is removed by the drum 17 and in passing under the heating element the rest of the moisture on the film is dried. Any

moisture that escapes Ythis Vtreatment must/j necessarily be on the under side ofi-the lilm and is removed in passing over the drum 11. The film then passes through the dry pads on channels 9 and l5 and is polished.

VFrom the foregoing description and construction of applicants device'it can be seen that it is capable of cheap production, that'itv does not require skill for its operation andY that it does not require any more effort than an ordinary rewinding operation. It is to be understoodthat the above described device is 'merely the preferred embodimentofappli cants invention in practice and is susceptible to suoli various `changes and modiiications Within the scope of applicantsA claims as he may deem advisable to practice.

Havingthus fully described the object and practical embodiment of the invention, what is desired to be is l. A lilm cleaning and' polishing device protected by Letters vPatent Vcomprising a base, a standard mounted on said base carrying channel plates, a bracket hingedly mounted on said standard and carrying channel plates for coacting With said iii-st mentioned channel plates to form lilin;

clamps, each channel plate carrying-soft absorbent material on its innerface and a heating element mounted on said bracket intermediate said channel plates and adjacent the line of travel of the film being cleaned.
